I haven't had that much issues. I can't say I didn't face any, but
they (almost) always had easy workarounds IIRC.

The main problem with GWT is that because developers don't see
JavaScript they think they don't even have to know HTML, JavaScript or
CSS, and sometimes even tend to forget they're coding a browser-base
app. Coding in Java means better (or, at least, different) tooling and
sharing code with the server (though it's moot as JavaScript tends to
come back to the server nowadays).

I've been told that Flash isn't a silver-bullet. Might be browser-
engine agnostic (though still depends on the browser's plugin API) but
not platform (OS) agnostic.

Internet Explorer is so strangely coded (with strong constraints on
backwards compat with its own bugs, embedded API, etc.) that it has
weird bugs that have to be solved on a case-by-case basis.

Given Internet Explorer's release schedule and update rate, you might
be dead and buried before it happens. Internet Explorer apart, it
might very well happen much sooner, if not already the case.
